CALENDAR PROVIDED WITH SEALS BACKGROUND OF THE INVENTION calendars have previously been employed, these calendars require a certain amount of time for ascertaining any day from the dates printed on the sheet. The monthly renewed calendars have no use for determining what day of the week a particular day is unless its date is known.

On the other hand, while the daily renewed calendar can provide todays date as long as it is renewed daily. a particular date in the past or in the future cannot be found quickly.

SUMMARY OF THE INVENTION A principal object of the present invention is to provide a calendar which overcomes the defects of the prior art calendars, such as indicated above.

Another object is to provide separable seals on a weekly chart printed on a base sheet so that the same effects produced by the daily renewed calendar may be further provided to monthly or yearly renewed calendars.

A further object is to provide a calendar which would enable any important date to be clearly recognizable.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a plan view of the calendar.

FIG. 2 is a plan view of the seal.

FIG. 3 is a sectional view of a modified form of the calendar, taken along the line 33 in FIGv I.

FIG. 4 is a plan view of a modified form of the calendar showing the underside thereof.

DESCRIPTION OF PREFERRED EMBODIMENTS An example of the invention applied to a monthly renewed calendar will now be described with reference to the figures. On a base sheet I, the days of the week 2 are imprinted on the uppermost row and the dates 3 are printed in the subsequent rows. Separable seals 4 are applied over the respective printed dates 3. By providing the base sheet (1) with a wax coating after the printing of the days of the week 2 and dates 3, the seals 4 may be readily peeled off without causing damage to the base sheet. This method of peeling off the seals 4 is by no means limitative, and any other suitable method may, of course. be employed. Also, the surface of the seal 4 may be printed with the same date as the one printed on the base sheet. By so doing, the effects of the monthly renewed (or yearly renewed) calendar may also be achieved.

Further, as shown in FIG. 2, the seal 4 may be printed with an advertisement 6. This is extremely effective for commercial purposes. since the advertisement can cas ll be seen while the seal as being removed. It is also possible to use a particular seal 5 of a different shape. or provided with a different color for indicating a holiday. birthday. annhersary or any other important day. The regular seals may be printed. for esample, in an to al shape and the special seals in a rectangular one. l3 preparing seals in such a manner. the special dates can be more easily noted and remembered.

As shown in FIG. 3, the back of the base sheet 1 may be backed with a cardboard or like thick paper sheet or plastic or wooden board 7.

If ordinary sheet paper is used, the base sheet I might warp on the sides provided with the seals 4. To alleviate this problem, the base sheet 1 can be backed with plastic, cardboard, or any other similar thick paper 7.

The printing of the days of the week 2 and the dates 3 may be accomplished either by direct printing on the 9 surface of the base sheet 1 or by printing reverse characters on the back of the base sheet 1 as shown in FIG. 4. The ink used in printing should penetrate the base sheet I so that the characters 8 printed on the back of the base sheet in reverse will appear on the front surface of the sheet when the seals are peeled off.

Accordingly, if the base sheet I is too thick, ink would insufficiently penetrate so that the impressions of the characters will not appear on the front surface. On the other hand, if the sheet is too thin, it is likely that ink will excessively blot, resulting in blurred and unclear figures.

The removal of the seals 4 may be facilitated by providing the front surface of the base sheet I with a suit able wax coating. The seals 4 are applied to the front surface of the base sheet 1 and over their respective impressions,

The surface of the seals may be printed with any character, drawing, or patterns for advertising purposes, and most desirably, with the corresponding date. In the monthly renewed calendar shown in FIG. I, seals printed with dates are applied at positions for corresponding weekdays, so that the dates of this month can be clearly seen. Thus, by peeling off a seal every day, the date of that day will appear on the base sheet, mak ing it readily apparent that today is the day before the day provided with the next sea].

It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.

What is claimed is:

1. In a calendar provided with the days of the month imprinted seriatim on a base sheet, the improvement which comprises a plurality of individual removable seals affixed onto said base sheet, the surface of each of said seals contacting with said base sheet being coated with an adhesive substance and the cooperating base sheet surface being covered with a waxy coating, each one of said seals covering a different day indicia whereby said seals can be individually peeled off of said base sheet to uncover the day imprinted thereunder, and wherein each of said seals has the same day imprinted thereon as the day imprinted on said base sheet underneath said seal, so that a viewer may ascertain at a glance exactly what date seals have been stripped from the calendar.

2. A calendar according to claim I wherein said base sheet is backed with a backing sheet.

3. A calendar according to claim I wherein certain of said seals are of a different shape to indicate special days differing from the remaining days.

4. A calendar according to claim I wherein the days are imprinted in reverse characters on the under surface of said base sheet. said base sheet being thin enough so that the days will be visible on the upper sur face of said sheet when said seals are removed there from.

said seals contain advertising material imprinted thereon.
